Since I switched to the WifiLogger I'm occasionally seeing dew points of -1 in my Weather Underground page.
see the graph here
https://www.wunderground.com/dashboard/pws/KTXODESS12/graph/2019-10-16/2019-10-16/daily (WU link)
(The summary also reflects -1 as the day's low dew point.)
This appears to have started only when I started using the WifiLogger.
Note that the -1 dew point seems to always be at the top of the hour or half-hour.
In the WFL setup, the update is 5 minutes (int: 5 seconds), RapidFire: Disabled
The -1 dew point does
not appear in my Weatherlink app data. Maybe there's something on the WU end that is causing this but, as I said, it has only started since I began using the WifiLogger in about August.
Has anyone else see this? Or have an explanation?
Thanks
